Script error replacing smart object layers if placed in group within layers panel

Report · May 08, 2024

Hello,

I have this script that works to replace smart object layers on the main layers panel, however if I place a smart object(s) into a group or folder, I am getting this error. hopefully there is an easy solution.

(see attachment)

Here is the script:

#target photoshop

app.activeDocument.suspendHistory("Relink Top-Level Smart Object Layers Using New Name Prefix.jsx", "promptAndReplace()");

//-------- Used in promptAndReplace() --------

function getSmartObjectReference() {
// https://stackoverflow.com/questions/63010107/get-a-smart-objects-layers-files-directory-source-in-js...
try {
var smartObject = {
found: false,
fileRef: '',
filePath: '',
linked: false,
};
var ref, so;
ref = new ActionReference();
ref.putProperty(charIDToTypeID("Prpr"), stringIDToTypeID("smartObject"));
ref.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt"));
so = executeActionGet(ref).getObjectValue(stringIDToTypeID("smartObject"));
smartObject.found = true;
smartObject.linked = so.getBoolean(stringIDToTypeID("linked"));
smartObject.fileRef = so.getString(stringIDToTypeID("fileReference"));
if (smartObject.linked) {
smartObject.filePath = so.getPath(stringIDToTypeID("link"));
} else {
smartObject.filePath = Folder.temp + '/' + smartObject.fileRef;
}
return smartObject;
} catch (e) {
alert(e);
return smartObject;
}
}

Line 51:

var so = executeActionGet(ref).getObjectValue(stringIDToTypeID("smartObject"));

As the active layer is a layerSet, there is no smart object value to retrieve.

So you would need to add a conditional check to see if the active layer is a layerSet, and if it is loop over the layers in the set.

Code snippets (code isn't fully functional, it's just an example):

// Check if the active layer is a group
if (app.activeDocument.activeLayer.typename === "LayerSet") {
    // Loop over the contents of the selected layer group
    for (var i = 0; i < app.activeDocument.activeLayer.layers.length; i++) {
    alert('Do stuff for layers in a group');
}
} else {
    alert('Do the same stuff for layers outside of a group');
}
